Precision Two-Component Adhesive Packaging for Aerospace Assembly

Challenge

An aerospace component manufacturer used a two-component epoxy adhesive for bonding structural components during assembly. The adhesive required precise mix ratios between resin and hardener to meet performance specifications.

Previously, technicians manually mixed the adhesive prior to application. This process introduced several risks:

• inconsistent mix ratios
• variability in working time
• additional labor requirements
• potential for batch documentation errors

Because the adhesive was used in aerospace applications, the manufacturer also required complete batch traceability and documentation.

Solution

Altaris Industrial implemented a two-component packaging configuration using dual cartridges. Each cartridge contained the correct proportions of resin and hardener separated into individual chambers.

When dispensed through static mixing elements, the materials combined automatically to produce the required mix ratio.

The process also included:

• controlled filling of dual-chamber cartridges
• traceable batch records
• compatibility testing with customer dispensing equipment

Results

• consistent adhesive mix ratios during assembly
• reduced preparation time for technicians
• simplified documentation and traceability
• improved reliability of adhesive bonding operations
